Abstract
The utility model relates to a hollow slender flexible power output shaft, which comprises a hollow shaft, a shaft coupler and a torque-measuring basic shaft and has the key points that at least two damping bosses are arranged at the proper positions of the hollow shaft, a torque measuring ring is arranged at the rear end of the hollow shaft, the height of each damping boss is 1 to 3 millimeters, and the length thereof is 15 to 25 millimeters. The utility model has simple structure, light weight, convenient balancing operation, high balancing precision and small vibration.
Description
Technical field
The utility model relates to a kind of running shaft, is specifically related to a kind of hollow elongated flexible power output shaft.
Background technique
In order to alleviate engine weight, the engine power output shaft mostly adopts hollow shaft, and the slenderness ratio of hollow shaft is increasing, and the aspect ratio of its endoporus is also just big more, this elongated hollow shaft is generally all worked under supercritical speed, bear tachometric survey, moment of torsion output, torque measurement etc.Because this hollow shaft slenderness ratio is big, when high speed rotating, the balancing rotor time is long, and balance quality is low, causes vibration exceeding the standard easily.Tachometric survey, moment of torsion output, torque measurement are single the measurements, cause the complex structure of this hollow shaft, Heavy Weight.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, little, in light weight, the balancing of vibration is convenient, can measure the hollow elongated flexible power output shaft of rotating speed and moment of torsion simultaneously.
Hollow elongated flexible power output shaft of the present utility model comprises hollow shaft, coupling and survey and turns round reference axis, it is characterized in that: the appropriate location of described hollow shaft is provided with at least two vibration damping boss, and the rear end of hollow shaft is provided with the survey torsion circle; Described vibration damping boss height is 1---3 millimeters, length is 15---and 25 millimeters.
The advantage of the more existing hollow elongated flexible power output shaft of the utility model is to be provided with the vibration damping boss, and the incorporate survey torsion circle of moment of torsion and rotating speed is simple in structure, in light weight, and balancing run is convenient, and the balance quality height vibrates little.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure 1, hollow shaft, 2, survey and turn round reference axis, 3, the vibration damping boss, 4, coupling, 5, survey torsion circle, 6, pin.
Embodiment
By shown in Figure 1, turn round reference axis 2 by hollow shaft 1 and the survey that is arranged in the hollow shaft 1, the hollow elongated flexible power output shaft that coupling 4 is formed.Survey is turned round reference axis 2 and is fixed on the front end of hollow shaft 1 by pin 6, and the front end of hollow shaft 1 is provided with coupling 4, and coupling 4 is the straight tooth column involute spline coupling joint.Be provided with two vibration damping boss 3 in the front end appropriate location of hollow shaft 1, the height of vibration damping boss 3 is 1.5 millimeters, and length is 20 millimeters, surveys torsion circle 5 by the rear end of dowel fixes at hollow shaft 1.During experiment, owing to set up vibration damping boss 3, the incorporate survey torsion circle 5 of moment of torsion and rotating speed, balancing run is convenient, and the balance quality height vibrates little.
